Write down the sequence of steps you used to find the solution to problem 4.1. Try to use mathematical symbols an no just words to describe your steps.
This is my sequence of steps
195=30+15N 195-30=15N 165=15N N=165/15 N=11
Make a problem similar to problem 4.1 and solve it using your method from question 1.
